These are definitely the nicest and most comfortable sandals Ive ever owned. I ordered a size 9 because my other Crocs are a 9, and these do fit, but I think they could fit a little more snugly -- I have a little space at the back. But texts go through just fine That was pretty difficult considering how tiny the beads were. I bought 4 sets of wheels, 2 green sets and 2 blue sets. These seems to pass the online tests of authenticity, but everywhere I read online says not to order on Amazon b/c most are counterfeit. This unit was easy to put together and was exactly as advertised! one more important thing to know, these are SEMI-OPEN headphones. They seem like they will last a lifetime. Great if you do a lot of travel or need something to cut out background noise and studying.
